======= Disease Resistance =======
The risk of getting a negative effect from a disease is reduced by this value. 100 means the unit will be totally unaffected, just like an undead being.

The value is a percentage, and it is rolled fresh every time a disease would do something. The game rolls a number from 0 to 99, and below the value the disease event is cancelled outright. Almost every creature that has the ability has it at 100, so it usually reads as plain immunity. The [[bless|bless]] picks **Half Dead** and **Strong Blood** are the exception: both grant 80, which cancels four events in five and cures nothing.

===== What it is rolled against =====

  * **Catching a disease.** The [[auras#plague|Plague]] aura and the spell ??Plague??, the disease a [[reaper|Reaper]] spreads through the province it stands in, attacks that infect their target, and the random events and dominion effects that disease the units of a province. For Plague this is a second saving throw on top of the [[magic-resistance|Magic Resistance]] check and is rolled after it, so either roll alone is enough to escape.
  * **Suffering a [[afflictions#torso-afflictions|disease]] already caught.** The roll comes before the monthly damage, and a success skips that month entirely.
  * **The battlefield plague.** The damage and fatigue the Plague effect inflicts round after round is rolled against Disease Resistance as well.

The Miasma dominion of MA C'tis is an exception of its own: it reads the value but never rolls it. Anything below 100 is diseased all the same, so the 80 from a bless gives no protection there.

The one thing it does **not** cover is the disease clouds of a [[auras#plague-carrier|Plague Carrier]]. Those inflict the affliction on a failed [[magic-resistance|Magic Resistance]] check and never look at Disease Resistance, so even a creature with 100 becomes diseased when it stands in one. What saves it is the next point.

===== Value of 100 cures the affliction, it does not only prevent =====

Disease Resistance of 100 removes the disease itself. A diseased creature that has it loses the affliction at the start of the next turn, before any damage is rolled. So a Plague Carrier's cloud can leave such a creature diseased for the rest of a battle, and the affliction is gone by the following turn without ever having cost it anything. A value below 100 does not cure: a creature with 80 that catches a disease keeps it, and rolls against it month after month.

===== Who has it =====

Four kinds of creature count as Disease Resistance 100 whatever their listed value:

  * [[demon|Demons]]
  * [[spiritform|Spiritform]] creatures
  * Stone beings
  * [[inanimate|Inanimate]] creatures that are not [[undead|undead]]

[[undead|Undead]] are a separate case. They are not counted as resistant, and a disease cloud marks them diseased like anything else, but a diseased undead is skipped by both the monthly damage and the battlefield plague, so the affliction never costs them anything either.

Having no resistance has one visible consequence. Only a value of 100 clears a disease, and an undead creature reaches 100 only if it is also on the list above, in practice by being [[spiritform|Spiritform]] or a stone being. No undead in the base game is also a [[demon|demon]]. Every other undead that catches a disease **keeps it until a [[disease-healer|Disease Healer]] removes it**: the mark stays on its sheet, and it never does anything.
